To ALL wHou rr MAY eonenRN:

Be it known that I, WILLIAM H. NOYES, ci' Franklin, in the county ofVenango, and State of Pennsyll Vania, have invented a new and usefulImprovement in Pumps; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawing, which is made apart of this specification, andwhich represents a vertical longitudinal section of a pump illustratingmy invention.

' In the ordinary tubular pumps the upper valve-seat is recprocated withthe plunger, while the lower valveseat maintains its position at or`nearthe bottom of the tube. In this condition the lower valve is liable tobe clogged and impaired in operation by gravel, etc., in water and'oilwells, and hy grain when used in a ships pump. In my improved pump thearrangement is reversed, the upper valve-box being stationary, and thelower one movable with the plunger, the rod of the latter passing upthrough the upper valve and valve-box, and being provided with a xcdcollar, so that by means of the plunger-rod the entire apparatus may beintroduced and properly adjusted in operating position, or withdrawnfrom the tube for repair or other purpose.

In order that others skilled in the art to which my invention appertainsmay be enabled to fully understand and use the same, I will proceed todescribe it in detail.

In the drawing, A may represent a. pump-barrel, and B a section oftubing connected thereto in customary manner. C represents the plunger,which carries. a. ball-valve, D, opening upward, and which is attachedt0 the lower `extremity of the plunger-rod Ef Hence, as the plungermakes its upward stroke, it carries with it the lower valve and its box,and the said valve is thereby made less liable to become clogged thanit'would be if permitted to remain at the bottom of the pump-barrelduring the operation. F represents the upper valve, which is a centrallyperforated disk having its lower surface ground to fit a seat, F',formed for it in the upper part oi' the box G, which may be slightlytapered from top to bottom to adapt it to be tightly wedged into theupper end of the pump-barrel by the downward action of the iXed collar Eon the plunger-rod.

In operation the plunger-rod E plays through the centre of the box G andupper valve F and sca-t F', and as the plunger rises the lower valvecloses, and the upper one opens. When the plunger descends thesuperincumbent weight of the elevated liquid holds the upper valveAsnugly to its seat while the lower valve opens and admits liquid intothe pump-barrel between the valves, where it remains until forced upwardthrough the upper valve by the ascent of the plunger. It will be seenthat in withdrawing the plunger und lower valve from the pump-barrel andtubing, the forcible elevation of the same will serve also to dislodgethe plug G, together with thel upper valve and box G, and thus theentire apparatus is withdrawn at once. Likewise, in the act of insertingthe apparatus, the collar E is made to carry down the box G withsuliicient force to wedge :it securely in its operating position'at theupper part of the pump-barrel. This pump has been well tested, and withit more successful results have been attained than with any other withwhich I am acquainted.

Having vthus described my invention, the following is what I claim asnew herein, and desire to secure by Letters Patent:

The pump herein described, constructed-with a collar, E', upon theplunger-red E, a valved plunger, C D,

and :twelve-box, G, adapted to be removed by the plunger C and forceddown into the converging pump-barrel A by the -collar E', allsubstantially as and for the purposes herein specified.

To the above specilicaton of my improvement I have signed my hand this30th day of Marcil, 1867. WM. H. NOYES. Witnesses:
